[u]The Story[/u]

My girl and your guy have been best friends for a long time. They've known each other since children and even made a pinky promise that when they grew up they would get married. They dated in their teens and were each other's first kiss but it ended when her parents moved her away. He was never told why.

Now present day, she has moved back and the two are now room mates with each other as she doesn't have anywhere else to live. The only problem? The guy has a steady girlfriend who is probably expecting him to pop the question, until SHE turns up – the mysterious girl that she could never live up to. And he will learn why she moved away to protect him and the reason she is now back – she has special gifts. A sixth sense and she would spend her life being hunted by people. She moved away to protect him from the horrors of this world. But now she has grown and learned how to deal with the evils in the world and came back because his life is now in danger. Only she could only ever be there for him as a friend and it's killing her to see him with another woman.

History: Victoria, or Varia for short, grew up relatively normal until she was sixteen. She grew up with her best friend *your character name here* and grew romantically close to him during their high school years. He was her first crush and then finally after years or keeping her feelings hidden from him, she found out he felt the same as they shared similar interests. They shared a momentary kiss before their relationship could full flourish and she moved away without so much of a word. She wasn't allowed to keep in touch. She found out she had special powers of something of a supernatural nature. She was forced to move away as any chance of friends, the forces of evil would seek to use them against her. She couldn't bare thinking about something happening to him because of her. 

During those 8 years away she trained hard under the tutelage of Rani, a beautiful Indian Bollywood dancer ten years her elder, who practices witchcraft and voodoo. She learned a lot on how to fight using her powers. And when she had a premonition revealing her best friend and childhood romantic interest was in danger, she quickly moved back to the city. She found herself on his doorstep without any place to stay. She was so happy to see him, and he had matured since she'd last seen him and her feelings for him sky rocketed. Only to be crushed to find out he was living with his girlfriend Amalia of 3 years (open to length). And that was two months ago. Since then she found herself a job as a dancer in a theater due to her grace and agility side of her special gifts. But she is finding it hard to be around him and Amalia as she has these deep feelings for him that never went away from the beginning. Although, her powers are starting to make her distrust Amalia as she lives (temporarily) in their spare room and Amalia is keen for her to move out and get a place of her own as she feels threatened by her. She wont let the two be alone for too long as she sees the way Varia looks at him across the room. Amalia was always hearing stories about V and could never live upto her in his eyes.

Feel free to add of your own NPCs to that list as well. And it's upto you how much supernatural we do add in. 

PM me your own ideas for an Affair type story if this isn't quite up your alley. I do like a variety of settings/stories from Medieval to Futuristic sci-fi. Doesn't have to be any supernatural.
